Piotr Nowojski created FLINK-29645:
--------------------------------------
Summary: BatchExecutionKeyedStateBackend is using incorrect
ExecutionConfig when creating serializer
Key: FLINK-29645
URL: https://issues.apache.org/jira/browse/FLINK-29645
Project: Flink
Issue Type: Bug
Components: Runtime / State Backends
Affects Versions: 1.14.6, 1.15.2, 1.13.6, 1.12.7, 1.16.0, 1.17.0
Reporter: Piotr Nowojski
{{org.apache.flink.streaming.api.operators.sorted.state.BatchExecutionKeyedStateBackend#getOrCreateKeyedState}}
is using freshly constructed {{ExecutionConfig}}, instead of the one
configured by the user from the environment.
{code:java}
public <N, S extends State, T> S getOrCreateKeyedState(
TypeSerializer<N> namespaceSerializer, StateDescriptor<S, T>
stateDescriptor)
throws Exception {
checkNotNull(namespaceSerializer, "Namespace serializer");
checkNotNull(
keySerializer,
"State key serializer has not been configured in the config. "
+ "This operation cannot use partitioned state.");
if (!stateDescriptor.isSerializerInitialized()) {
stateDescriptor.initializeSerializerUnlessSet(new
ExecutionConfig());
}
{code}
The correct one could be obtained from {{env.getExecutionConfig()}} in
{{org.apache.flink.streaming.api.operators.sorted.state.BatchExecutionStateBackend#createKeyedStateBackend}}
